Hundreds of students barricaded school entrances across Paris and held demonstrations on Thursday against alleged police brutality.
It’s the latest in three weeks of protests since the death of 21-year-old botany student Remi Fraisse.
He was killed during a march against plans to build a dam in southwestern France. His death has been blamed on a stun grenade fired by police which hit him in the back, getting lodged between his back pack and clothes before exploding.
Protesters say Francois Hollande’s government has blood on its hands and tried to cover up the facts.
Leaked recordings of conversations show police knew straight away that a man had died. However the police and government did not confirm the death until 48 hours later.
The controversial dam project in Sivens would destroy a biodiversity reservoir but those in favour of it say it will ensure irrigation for local farmers.
